<P>PROBLEM TO BE SOLVED: To provide a liquid pump that can be manufactured by a simple process, has small flow path resistance, and achieves improved pump efficiency. <P>SOLUTION: The liquid pump 100 includes: a first housing 20 for freely rotatably supporting a shaft 10 via a bearing 11; an impeller 30 fixed to one end of the shaft 10; and a second housing 21 joined to an open end surface of the first housing 20. The bearing 11 and the shaft 10 are integrally molded with the first housing 20 by insert molding. The first and second housings 20, 21 are joined to each other by a resin material 23 filled into each annular groove 24 provided on each open end surface of the first and second housings. The resin material 23 filled into the annular grooves 24 extends along the open end surfaces to the outer peripheral surfaces of the first and second housings 20, 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
